Depends on one's definition of determinism. If you need the entire state of the system to calculate the next state, it's still deterministic, just not local.
The thing about QM is that it may be a bit different, you can have a function ("laws of the universe") which instead of producing one next state, it produces multiple states and those states could produce multiple states as well and so on, but the obserer will of course only observe a single state (the one he is in), thus he will observe randomness along the lines of which state was chosen. It's still unclear if this is the case for our world, but it is one possible interpretation of quantum mechanics.
